People have taken to social media to report menstrual changes after getting the COVID-19 vaccine, and while the jury is still out on if it’s directly related to the vaccine, experts say it is because women have more robust immune responses to vaccinations.
Women’s health and immunology experts are hesitant to say if menstrual changes are a result of the COVID-19 vaccine until further research is conducted, but noted that the added stress of the pandemic may contribute to shifts in one’s menstrual cycle.
“I think it's likely attribution. In other words, when two things happen, we tend to think they're related, and they may not be,” Dr. Jerilynn Prior, professor of endocrinology at the University of British Columbia and Scientific Director of the Center for Menstrual Cycle and Ovulation Research, told CTVNews.ca in a Zoom interview.
Menstrual changes can happen for a number of reasons, one of which is stress, which many people have been under since the coronavirus pandemic started.
The sheer relief of being able to get vaccinated could also lead to adjustment’s in one’s cycle.
Of the data collected on menstrual cycles during the pandemic, experts say it reflects more disruptions than usual.
